What is a Transition Lens? and How Does a Transition Lens Work?
What is a Transition Lens?
Transitions lenses are photochromic lenses that are clear indoors and when you go outside and get direct exposure from UV rays, they activate (get dark). I've told you about it, but now I want to show you how this process happens within a period of 45 seconds (in this case, much less than 45 seconds).
Look at this, direct exposure to UV rays. I'm using my finger to cover part of the lens to block the rays from activating the part of the lens covered by my index finger. When I remove my finger, you notice that it didn't activate. The transitions or photochromic lenses have to have direct exposure to UV rays. So that is what a transition lens is!
How Do Transition Lenses Work?
How is it? it's fascinating. The answer is that it is a carbon based organic compound injected to the front surface of the lens. It is not spread across the entire thickness of the transitions lenses. It is just in the front surface and it is spread evenly throughout the thin layer.
Keep in mind when deciding on whether or not to get a transition lens that how dark the transition lenses get is inversely correlated with the ambient temperature. That means that if you are in 40 degree fahrenheit weather, the transition lenses will get darker than if you are in 110 or 100 degree weather.
How Long Does Transition Lenses Last?
Under normal wear and tear, the transitions lenses are going to last around 2 years. Some people that use them quite a bit, they'll last less. For the most part, it's around 2 years for their shelf life.
Final Thoughts:
Transitions or photochromic lenses are great to have in your wardrobe of eyewear. They have a purpose, but what they don't do is they don't completely replace your sunglasses.
So make sure you still have a pair of polarized sunglasses that protect you against the sun's harmful rays and filter light in a way that they eliminate all light coming in from oblique angles. This is what makes polarized lenses superior to transitions lenses outdoors.
Transition lenses are great and you should have a pair.
Then, I perform a magic trick (thanks to fancy editing, LOL)
